DENVER — When the largest church in Boulder County, Colo., wanted to double its size two years ago, county commissioners said no.
Rocky Mountain Christian Church already dominated a rural corner of the county northwest of Denver. If it became any larger, commissioners said, it would destroy the area's country atmosphere.
But the church didn't accept the decision quietly. Using a relatively new federal law meant to protect religious organizations from discrimination by local governments, church officials charged Boulder County with hampering their ability to practice their religion.
The county responded by calling the law unconstitutional because it prevented communities from controlling their growth and planning.
This month, the conflict reached a federal courtroom in Denver, where a jury will begin deliberating the case today.
Although such cases have cropped up around the country since the Religious Land Use and Institutionalized Persons Act was passed in 2000, legal experts say they rarely advance to the courtroom.
The Supreme Court has not heard a land-use case under the statute, but lower courts generally have ruled that the law is constitutional, said Patricia Salkin, associate dean and director of the Albany Law School Government Law Center in New York.
One issue, she said, is that the law says governments can't place a "substantial burden" on the right to practice religion but doesn't adequately define substantial burden.
Many cases have focused on whether a church can locate in a particular area, but the Boulder County case is one of the first to deal with the size of a religious institution, Salkin said.
In 2006, Rocky Mountain Christian Church announced plans to add a children's wing, gymnasium, rooms for adult classes and 500 parking spaces. The expansion would have brought the church's square footage to 240,000. The expansion was planned for land it owned in the county's agricultural buffer between urban and rural areas.
Boulder County officials, known for aggressively preserving open space and rural land, agreed to a small expansion of the church sanctuary but denied the rest, calling it "completely out of character" with the area.
County officials pointed out that they had approved five expansion requests from the church over 10 years. This one "so clearly fell outside the regulations . . . that no entity or institution requesting such an expansion would've been approved," county officials said in a statement.
